In-mold labeling is a method favored by many friends in China, and its label materials include film and paper. Let's take a look at what film materials are used for in-mold labeling?
BOPP: This material is biaxially stretched and has a special coating on the surface. It has good printability, but the in-mold label is easily deformed when labeling a large area on a container. If the container material is PE and the in-mold label material is BOPP, due to the different shrinkage rates of the two, orange peel will appear after labeling.
PE: This kind of material is not stretched, the surface needs corona treatment, the printability is poor, and the material deforms greatly after hot stamping. It will not deform when labeling on PE containers.
PP+PE: This material has been uniaxially stretched, and the surface of the material needs to be corona treated. It has good printability and stable printing tension. Since the material contains PE components, it is required to use hot stamping foil with a lower hot stamping temperature during hot stamping. This kind of material can achieve better labeling effect: smooth surface, no deformation, and beautiful appearance. The above is about removing film materials. I hope the above knowledge can help everyone understand it. If you need it, you can also contact us to purchase in-mold stickers.
